What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPreventive strategies aim to reduce older adults' emergency department (ED) visits and related adverse health outcomes, but their impact on healthcare system utilisation remains unclear. This can be investigated using system dynamics modelling, which uses data to explore effects and test strategies across populations.
aimIn this study, we simulated and studied how preventive measures affect acute hospitalisations, intermediate care, home care, and nursing home admissions among community-dwelling older adults after an ED visit.
methodsWe developed a system dynamics simulation model tracing older adults from ED visit to hospitalisation, intermediate care, discharge home (with or without care), nursing home admission, or death within 30 days. Simulated strategies included proactive care, geriatric emergency medicine, and hospital-at-home. Data from Amsterdam residents aged ≥65 who visited the ED in 2019 were used. Patients were categorised by home care status.
results31,049 patient journeys were used in the modelling. Of the simulated strategies, hospital-at-home demonstrated the largest potential reductions in institutionalised care use after ED visits in the total cohort: acute hospitalisations (-10.2%), intermediate care (-16.7%), nursing home care (-10.7%). Furthermore, it showed a reduction in personal home care (-1.8%), and limited increases in household help (+2%) and nursing home care at home (+1.5%).
conclusionOf the simulated strategies, hospital-at-home reduced healthcare use post-ED most effectively, causing the greatest decrease in institutional care without requiring a meaningful increase in home care services during one year of follow-up.These findings can guide policymakers, insurers, and institutions in choosing effective preventive strategies for regional populations.
